RESUMEN
Chest pain is one of the chief presenting complaints among patients attending Emergency department. The diagnosis of acute myocardial infarction may be a challenge. Various tools such as anamnesis, blood sample (with evaluation of markers of myocardial necrosis), ultrasound techniques and coronary computed tomography could be useful. However, the interpretation of electrocardiograms of these patients may be a real concern. The earliest manifestations of myocardial ischemia typically interest T waves and ST segment. Despite the high sensitivity, ST segment deviation has however poor specificity since it may be observed in many other cardiac and non-cardiac conditions. Therefore, when ST-T abnormalities are detected the physicians should take into account many other parameters (such as risk factors, symptoms and anamnesis) and all the other differential diagnoses. The aim of our review is to overview of the main conditions that may mimic a ST segment Elevation Myocardial Infarction (STEMI).

AIM: The metabolic syndrome (MS) is associated with increased cardiovascular and cerebrovascular risk. This study aimed to compare the difference of the three established diagnostic criteria of MS, developed by Adult Treatment Panel III (ATP III), American Heart Association (AHA) and National Heart Lung and Blood Institute (NHLBI), and International Diabetes Federation (IDF), with regard to the prevalence of the syndrome and the ability to correctly identify individuals with cardiovascular or cerebrovascular disease or subclinical atherosclerosis. METHODS: We studied 947 consecutive patients underwent clinical evaluation between the 1997-2002. The project design included a medical assessment, biochemical analyses and the ecocolordoppler examination of carotid arteries. RESULTS: The MS prevalence was 37% in ATPIII subjects, 36% in AHA/NHLBI subjects and 43% in IDF subjects. Excluding patients with diabetes (N.=259), the MS prevalence ranged from 32% (ATPIII and AHA/NHLBI subjects) and 40% (IDF subjects). By most criteria, MS-positive subjects had significant incidence of carotid atherosclerosis (P<0.05) and cardiovascular events (P<0.05) than MS-negative subjects, but not cerebrovascular events. Finally, patients with MS had higher serum levels of fibrinogen (P<0.04). CONCLUSION: Subclinical atherosclerosis and cardiovascular events were increased in presence of the MS, irrespective of the several definitions.

The management of carotid artery disease includes both modifications in life style as well treatment of vascular risk factors. However, strict risk factor modification, including improved antihypertensive therapy, lipid management, smoking cessation, and antiplatelet therapy, promise for reducing the vascular event rate in patients with carotid atherosclerosis. The best medical management for stroke prevention was highlighted in clinical practice guidelines issued jointly in 2006 by the American Heart Association and the American Stroke Association, and co-sponsored by the Council on Cardiovascular Radiology and Intervention and the American Academy of Neurology. Lowering blood pressure to a target below 120/80 mm Hg by life style interventions and antihypertensive treatment. Glucose control to near-normoglycemic levels (target hemoglobin A1C ≤7%) is recommended among diabetics to reduce micro-vascular complications and, with lesser certainty, macrovascular complications. The primary objective of this review is to summarize the current evidence and standards for the advanced diagnostic and management strategies used in asymptomatic and symptomatic patients with carotid atherosclerosis.
